Alista Galaxy

The Alista Galaxy was a galaxy over 5 billion light years away from the Skyriver Galaxy. It was settled by the Continuals in 2,550,700 BBY.

History
The Continuals built the Umma within the Alista Galaxy, and created numerous starspheres around stars in galaxy.

Eventually, the Continuals transported the Prodigal Galaxy into it's vicinity, causing the two galaxies to collide, creating the Jadis Ellipse. The Continuals sought to add the Reditia Galaxy to the Jadis Ellipse as well, but were stopped from doing so by the Force in 99,811 BBY. After returning the Reditia Galaxy to it's original location, the Continuals spent 100,000 years separating the Prodigal Galaxy's star systems from those of the Alista Galaxy, eventually managing to return the former to it's original location in 189 ABY.

The sudden separation of the Jadis Ellipse into two separate galaxies caused a great deal of reasearch among spacefaring civilizations within those galaxies, eventually resulting the development of wormhole travel between the two galaxies in 311 ABY.
